PNEUMATIC TIRE.

SPECIFICATION brmjng part of Letters Iliatent No. 734,913, datedJuly 28,1903.

Application filed September 9, 1902. Serial No. 122,699. (No modeLl Toall whom it mayr concern:

Be it known that I, ARTHUR H. MARKS, a citizen of the UnitedStates,residing atAkron, in the county of Summit and State of Ohio, haveinvented a certain new and usefuluImprovement in Pneumatic Tires, (CaseB,) of which the following is a full, clear, and exact description,reference being had to the accompanying drawings. Y

The object of this invention is to provide in very simple and elicientform a pneu- 'matic tire having an outer sheath securely held to the rimwhether the tire be in tlated or not, but capable of ready removabilitywhen desired. In automobile use especially it is extremely desirable notto rely on the inliation of `the tire to hold it in place, for in thatcase a puncturewhen the machine is run-ning rapidly is very liableto'cause an accident byreasonof the tire leaving the rim. In myinvention,- as stated, the tire is securely held to the rim whetherinflated or not; and the invention consists of the means employed tothis end, which also allow the tire-sheath to be readily removable andprotect its edges when in place. This is hereinafter described, andfully set out in the claims.

The drawings clearly illustrate my invention, Figure l beinga sideelevation of a portion of my tire in placeon` the wheel-rim.

" of these members taking into the other.

Fig. 2 is a transverse section of the same, and Fig. 3 is a section of amodified construction.

Referring tothe parts by letters,-A represents a wooden rim surroundedby a metal band B, these parts being of usual form.

C is an inner pneumatic tube, and around this is the outer sheath D.This sheath extends inward, asat d, on opposite sides of the rim A. Sideplates E are placed outside ot' the portion d ot'` the sheath and areheld thereto by bolts F, passing through the-side plates, sheath, andrim and taking on their ends nuts f. 1

The sheath and the side plates E are looked together in operation by`pins carried by Ollie the form shown in Figs. 1 and 2 these pins G areembedded in the Hat portions d of the sheath, andthey have smallerextensions g, taking into holes in the side plates E. In the form shownin Fig. 3 the pins G are rigid with the side plates, projecting intoopenings therefor in the sheath. In either event the sheathing issecurely interlocked with the side plates, and the side plates beingheld at the rim by bolts securely hold the tire in place whetheriniiated or not. The sheath may be very easily removed for repair. sideplates E in section, so that in case of a puncture it may only benecessary to remove a portion of one side.

The side plates E are curved away from the sheath at their outer edges,as at e, to preventcutting the sheath when -pressu re is upon the tire,while at their inner edges these plates curve inward, as at e', beneaththe sheath, abutting the rim at this point. This latter inwardcurve notonly gives. a very neat appearance to the tire, but it protects theiuneredge 'ofV the sheath.

I claiml. In a detachable pneumatic tire, the combination of a rim, aninner tube surrounding the same, a sheath outside of the inner tubeextending onto opposite sides of the rim,plates removably carried onopposite sides ofthe rim, bolts extending through said rimtor holdingsaid plates in place, and short pins for locking the sheath to' theplates, said pins being carried by one of such members at pointsOpposite the sides of the rim, substantiallyl as described.

2. In a detachable pneumatic tire, the com# bination of a rim, an innertube surrounding the same, a sheath outside of the inner tube andextending onto opposite sides of the rim,

For this reason I prefer to make the.

pins carried by said sheath having reduced y outer extensions, andremovable side pilates having openings into which said extensions take,and means for holding said side plates in place, substantially asdescribed.

3. In a detachablepneumatic tire, the combination of a rim, an innertube surrounding the same, a sheath outside of the inner tube andextending onto opposite sides of the rim, In testimony whereof Ihereunto affix my oinwardly-extending short pins carriedy by signaturein the presence of two Witnesses. said sheath at points opposite thesides of the f rirn, removable side plates having openings l ARTHUR H'MARKS' 5 into which said pins take, and bolts passing VVtnesses:

through the rim for holding said side plates D. GALEHOUS, in place,substantially as described. I O. HART.
